Conform to Government Standards
The DSS ensures you meet government safety regulations without wheel chocks or restraints.
OSHA's wheel-chocking requirement for commercial vehicles as defined by FMSCA's wheel-chocking regulation are preempted by FMSCA's braking regulation. See [29 CFR 1910.178 (k)(1)], [49 U.S.C. 31132] and [49 CFR Part 393], respectively. |

Step 1
Lock the Trailer Brakes
The SGL is the cornerstone to the DSS system. This patented design will only allow the key to release once the SGL is applied to trailer Glad Hand coupling.
Once the SGL is locked on it ensures that the trailer brakes are applied, preventing unscheduled departures. Only then can the large heavy duty DSS key be released. |

Step 2
Open the Loading Dock Door
Option A - Outdoor Automatic Solution
The key released from the SGL in Step 1 is inserted into the DSS Control Panel (SCP). This sends an electrical signal to unlock the dock door and to internal and external traffic lights that provide clear communication to the truck driver and your dock workers.
Solutions available for power and manual doors.
Option B - Manual Indoor Solution
The key released from the SGL in Step 1 is brought inside and inserted into a mechanical lock (SMDL) that directly unlocks the door.
An additional option is to add electrical contacts to the mechanical lock (SMDL- E1). The contacts can be used to switch traffic lights, lockout motor controls for power doors and/or interlock powered dock levelers. |

Step 3
Safely Load/Unload & Depart
While the door is open the key is trapped
...in the SCP if Step 2 - Option A
...in the SMDL if Step 2 - Option B.
The key cannot be released until the dock door is closed, loading has finished and most importantly, after the dock workers are safe.
Now that the door is closed and the key is free, the key can be taken to the trailer to remove the SGL lock from the brake line. Once removed, the truck may safely depart. |
